KCNA Cloud Native Observability Practice Question
In OpenTelemetry, which component is responsible for receiving, processing, and exporting telemetry data from multiple sources?
⚠ Common exam trap
KCNA often tests the distinction between the Collector and other OpenTelemetry components, and candidates may confuse the Collector with the SDK or exporter, forgetting that the Collector is the only component designed to receive, process, and export data from multiple sources.

Correct answer & explanation
✓
OpenTelemetry Collector
The OpenTelemetry Collector is a vendor-agnostic proxy that can receive, process, and export telemetry data from multiple sources. It supports various receivers (e.g., OTLP, Jaeger, Prometheus) to ingest data, processors to modify or filter it, and exporters to send it to backends. This central component decouples instrumentation from backends, enabling flexible pipelines.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
OpenTelemetry Collector
Why this is correct
The OpenTelemetry Collector receives telemetry via receivers, processes it through processors such as batching, then exports it to backends. This satisfies the stem's requirement to handle data from multiple sources, acting as a vendor-neutral pipeline between instrumented services and observability platforms.
- ✗
OpenTelemetry SDK
Why it's wrong here
SDK is used for instrumentation, not data collection.
- ✗
OpenTelemetry Exporter
Why it's wrong here
An exporter only transmits already-collected telemetry to a backend; it does not receive from multiple sources or process data. It is tempting because exporting is one stage of the pipeline, and would be correct when configuring where a Collector or SDK sends its data.
- ✗
OpenTelemetry API
Why it's wrong here
API defines interfaces for instrumentation.
